C++ 课程设计 图书管理系统 题目 代码

C++课程设计是每个计算机科学专业学生必不可少的一项任务，它不仅可以帮助学生巩固所学的知识，还可以锻炼学生的编程能力。而作为一门实用性较强的课程，图书管理系统是C++课程设计的常见题目。下面我们来分享一下一份图书管理系统的题目及代码。

题目：设计一个图书管理系统，要求实现以下功能：

1. 图书馆藏书量的查询、增加、删除、修改等功能。

2. 图书借阅、归还的管理，可以记录借阅者的信息，包括姓名、借阅时间、归还时间等。

3. 借阅者信息的管理，可以查询、增加、删除、修改借阅者的信息。

4. 生成图书借阅、归还记录。

5. 界面友好，操作简便。

代码如下：

#include

#include

using namespace std;

struct Book

  string name;

  string author;

  string id;

  int count; // 图书馆藏书数量

  string phone;

;

struct BorrowRecord

  string borrower_id;

  string book_id;

  time_t start_time;

  time_t end_time;

;

vector library; // 图书馆藏书

vector borrowers; // 借阅者信息

vector records; // 借阅记录

// 从文件中读取图书馆藏书信息

void readLibrary() {

  ifstream file("library.txt");

  Book book;

  while (file >> book.name >> book.author >> book.id >> book.count) {

  }

  file.close();

}

// 保存图书馆藏书信息到文件中

void saveLibrary() {

  ofstream file("library.txt");

  for (int i = 0; i < library.size(); i++) {
